1) 2x + 35 = 180° so x= 180 - 35 / 2 =73°

the answer is 73°

2)

All right triangles are isosceles, that is false

3) In geometry, "Corresponding parts of congruent triangles are congruent" (CPCTC) is a succinct statement of a theorem regarding congruent trigonometry, defined as triangles either of which is an isometry of the other.
CPCTC states that if two or more triangles are congruent, then all of
their corresponding angles and sides are congruent as well. CPCTC is
useful in proving various theorems about triangles and other polygons.


If triangles ABC and DEF are congruent, denoted as
